[Possible use of stable tracers in hematological research. Preliminary note]

The aim of the paper was to verify the possible use in blood cells labeling both of stable K analogue elements and of stable compounds employed in nuclear medicine. The technique of analysis by XRF has been utilized. The paper presents some data obtained labeling red cells with Rb. The results indicate that in vitro red cells labeling with stable elements is a valid tool in the field of haematology.
